river . I have many friends :animals ,trees , and lovely children . Everyday we play together . Children swim. The animals sing . All of us are very happy and we are never tired . But one day , a big factory was built near my body . The birds and the fish had to move their houses , because of the dirty water and heavy smoke. My friends went away. I was so sad. Some years later. People woke up. They began to know that clean water is so important. Little by little , I found I was clean again . Now the water is clean and green . The air is fresh ,too . There are many fish in the river . And there are some bridges over the river . Rainbow Bridge is very beautiful. I love her very much . look !
